利用FLUENT软件采用标准k-ε湍流模型对喷射式布袋风管的送风情况进行了数值模拟研究.模拟计算了3种送风孔数和3种送风孔径下喷射式布袋风管的送风情况,得到了不同工况下布袋风管内静压的变化、室内风速的分布情况等.结果表明,沿布袋风管气流走向,风管内静压基本不变;随着送风孔数或孔径的增加,风管内静压显著减小,气流自送风孔喷出后衰减增大.%The flow distribution of jet fabric air duct system was studied by using the method of numerical simulation in κ-εturbulence model. Three types' number and diameter of orifice were simulated. The variations of static pressure in fiber duct and flow distribution were figured out. The results show that the static pressure in fiber duct keeps constant; with the increase of the number or diameter of orifice, the static pressure drops dramatically and the velocity reduces quickly.
